Moonlight wins best picture after announcement mix-up.

Moonlight has won best picture at the Oscars - but only after Faye Dunaway initially said La La Land had won.Warren Beatty was handed the previous winner's envelope, containing a card saying "Emma Stone, La La Land", resulting in the error.

The team from La La Land was in the middle of its acceptance speeches when the mistake was discovered.

Stone said backstage afterwards: "Is that the craziest Oscar moment of all time? Cool! It's going to be history."

PriceWaterhouseCooper, the accountancy firm responsible for counting the ballots, said in a statement: "We sincerely apologise to Moonlight, La La Land, Warren Beatty, Faye Dunaway, and Oscar viewers for the error that was made during the award announcement for best picture."

"The presenters had mistakenly been given the wrong category envelope and when discovered, was immediately corrected. We are currently investigating how this could have happened, and deeply regret that this occurred."
